Need help on GPS and SIRF/NMEA modes!

[silviu.h]

Hi all,

I have a problem... The GPS on my Athena worked, but I tried to fix it :rolleyes: I wanted to enable change the power mode to Trickle, so I installed SirfDemoPPC , changed the output mode to SIRF binary, and finally decided not to change the power mode, so I just hit Cancel, and changed the protocol back to NMEA.

Now I can't connect to the GPS anymore, Tomtom can't see it, and I don't know what is going on. I tried to connect SirfDemoPPC to all COM ports without success...

Please help!

There are two answers: Try looking in this thread http://forum.xda-developers.com/showthread.php?t=308606

Alternatively, try doing a hard reset (after backing up your data). The suggesiton is that setting GPS software to Sirf disables the GPS temporarily.

Don't use SirfDemo anymore - test out the GPS using GPSView or GPS Tuner.

Hi,

Don't worry about using SirfDemo anymore - I swear I'll never touch this piece of sh*i again (provided I get my GPS back to life).

I tried hard resetting, the problem is still the same. I will try removing the battery and letting the PDA lose its current. I read this *might* put the GPS receiver back into its initial state.

I also tried to contact the guy who made SirfTech, and try to understand what the error messages mean.

OK, I removed the battery for a night and now the GPS receiver came back to life... Problem solved :D

Something tells me I won't try any soon to change anything in the receiver :)

Hi,

What exactly is the problem: the GPS can't get a fix, or your programs (Tomtom etc.) cannont connect to the GPS?

In my case the problem was that the programs couldn't access the GPS anymore.

If your programs see the GPS but can't get a fix, it's a different problem.

Hope this helps,

hi, thanks for reply...

the GPS can't fix at all after 20 minutes....of course outdoor under clear sky
I'm using M700 Glofiish with built in GPS SiRF Star III chipset
I also tried using GPStuner as recommended above...still can't fix, not sure if it's software or hardware problem

one thing, i used SiRFtech...
1. there are signals from "Find Port & Baud"
2. Protocol: NMEA
3. Baudrate NMEA 0 Effective 0
4. Errors FE=0 PE=0 OE=0 QOE=0

???

any idea?

Thanks so much

Try the free GPSView program, that is the best for getting a FIX I find.
Make sure you use QuickGPS to download the data first as well.
Hold it up above your head and wave it at the sky?

I think there might be a problem with your unit, there are several people on the Eten forum who had this problem and had their M700 replaced. See http://eten-users.eu/index.php?showtopic=6586 and generally speaking http://eten-users.eu/index.php?showforum=42

try reflashing the radio on the device, GPS firmware is all controlled by that, so flash it and cross your fingers
